of operation, a further requirement beingl the insertion of an appropriate coin before the liquid can 'be released.

Gther objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in which Figure 1 is aperspective view villustrating the general external appearance of the apparatus, j

Figure 7 is a sectional view of the discharge and inlet valves in the foregoing position, l

Figure 43 is'a detail view of the coin receiver taken substantially on the line 8-8 of Figure'l.

A coi'nplete cycle comprises five distinct operations and in order-that there may be agreement of said operations with the manuullyv actuated mechanism of the apparatus, the parts involved are numbered in the sequence of said operations as follows: the initiating plunger 1. the pump handle 2, coin plunger 3, (Figs. 1 and 8), main plunger 4 and valve plunger 5.

Each of the foregoing parts is located, on the outside of the combined standard and casing 6 which both houses the mechanism and supports the glass container 7 in which the gasoline is'visible. It is herein assumed that the apparatus dispenses gasoline, but

as already indicated, it is adaptable to the l dispensation of other liquids.

The glass container 7 is suitablymounted upon the top 8 of the casing (F-ig. 5) upon which top it is cemented in place at 9 in circular groove 10. A `gasoline inlet pipe 11 leads from the pump casing 12 to the container 7, there beingan interposed three- Way valve 13 as shown for example in Figures 2 and 3. This valve is normally in position to place the container 7 and pump casing 12 in communication.

The pump casing 12 has a supply pipe` 14 which leadsto an underground storage tank (not shown). A pipe 15 serves as a kcommon tank return both to the container 7and to the pump casing 12. For the first purpose the tube 16 extends from the upper end of the pipe into the container in reference. `to Which its positions are adjustable so that variationsin the price of gasoline can be compensated )for as appears later. For the second'purpose the pipe 15 has a connection at 17 with the three-Way valve 13 so that continued operation ofthe pump after the valve position in Figure 7 has been assumed Will only result in the return of the gasoline to the underground tank.

f A discharge pipe 18` communicates with a flexible filling hose 19 which the purchaser uses to fill his gasoline tank. An interposed valve 20 controls the fio'w of gasoline. The handles of the inlet and discharge valves 13 and 20 are connected by a rod 2 1, the handle of the valve V13 comprisingga bell-crank 22 which has a lateral pin 23 which rides in the slot 21 of a finger 25 on' the valve plunger 5.' An extension 26 of the plunger 5 provides a lug which is engageable by the heel 27 ot' the initiating; plunger 1 when required to return the valve plunger to the initial position.

Assuming the valve plunger 5 to have been left pulled out (Figure 6) by a previous purchaser, a subsequent purchaser must first pull out on the initiating plunger 1 thereby returning the inlet and discharge valves 13 and 20v to the original position in Figures 2 and 3. The action is accomplished by the engagement of the heel. 27 with the` lu 26. The plunger 1 is slidably supported upon guides '28 in the casing.

After the required'amount of gasoline has been pumped into the container 7 the purchaser inserts the coin C in a slot 29 in the casing. The coin is thus introduced into what is generally known as the coin receiver. For the purpose of the present description the coin is assumed to be a silver dollar for which four gallons of gasoline may be purchased at 2.5 per gallon. The tube 1G makes rovision for variations in the price of gaso ine, and both the function and construction are brought out more fully later.

The coin receiver comprises a slotted head 30 carried by an arm 31 which is pivotally mounted at 32. The arm has an extension 33 to which the weight 34 is adjustably attached, and a lever 35 to which the coin plunger 3 is connected. The extension 33 normally rests against the stop 36. The counterweighl: 34 keeps the coin receiver in the normal position in Figure 8, but upon a pull on the coin plunger 3 the receiver is moved to the dotted line position. The coin receiver and the plunger 3 thereof occupy positions at right ang-les to the plungers l, 4 and 5 of the remaining mechanism.

The spring 37 and pivoted lever 38, resepctively situated at the ends of the slot in the head 30 complete a pocket by which the coin is receivable. IA spring 39 between the right end of the lever 38 and the arm 3l tends to rock the lever upon its pivot into the closing position. The coin IC when inserted into the ocket of the receiver, will be frictionally ield by the spring 37 and lever 38, but a coin or slug smaller in diameter than the standard silver dollar will not be held but will roll out into the slug chute 40 which leads directly to the slug box 41. Upon movement of the coin receiver to the dotted line position, noted before, the inner end of the lever 38 engages the stop `36 thereby releasing pressure upon the com C and permitting it'to drop into the coin chute 42. The coin chute stands at one side of the slug chute 40 SFi 8) but has a slug extension 86 which ea s to the box 4l also. The coin chute has an offset 87 which leads to the coin box 88.

A coin sto 43, operable across the extension 86 an normally in Lposition thereacross as in Figure 2 stops the coin C in position in front of the cupped end 44 of the rack 45. A pull upon the main plunger 4,.which is the act next in order after inserting the coin and pulling the plunger 3, rocks a bell-crank 46 upon its pivot 47 so that the hook end 48 thereof presses against the coin and thus against the cupped end 44 ofthe rack 45, resulting in the turning of the pinion 49 and lowering of a valve stop 50. The valve stop has a rack portion meshing with the pinion 49. The stop is suitably guided at 51 so that it nieves in plunger 5.

a rectilinear path.' It is normally engageable by a latch 52 pivoted on the va ve plunger 5 so that the valve plunger may not e pulled out prior to the proper time. The latch is held seated by a spring 85. The displacement of the valve stop permits pulling out of the valve plunger, and this act, as already stated, closes the inlet valve '13 to the upper part of the pipe 11 (Figs. 6 and 7 and o )ens the dise large valve 2l) so that the gaso ine may run out..

Motion ot' the main plunger 4 is transferred to the bell-crank 46 by means ot' a link 53 which is connected at the ends as shown. The collar 54 to which the lower end is connected engages one end of the spring 55 mounted on the plunger 4 and `bearing against the adjacent wall of the casing. This spring returns the plunger 4I when released, but the purchaser must hold the plunger 4 out until he. has begun pulling upon the valve )langer 5, otherwise the valve stop 50 woul return and prevent such pulling out of the lunger 5 by virtue of the reengagement of t e stop 50 willi the latch 52.

A heel 5G on the main plunger 4 displaees the coin sto 43 by the engagement with a lug 57 on tie coin stop when the plunger 4is'pulled out as described. Both the plunger and the coin stop have common support. upon a bearing 58, and a spring 5l) interposed between the lug 57 and the bearing serves to return the coin stop upon ultimate release of the main plunger 4. This release of the plunger and consequent relaxation ol pressure of the hook end 48 upon the coin permits the coin to fall from engagement with thecupped end 44 and to drop into the ollset continuation'87 of the coin chute 42.

It is anticipated that an atteni )t might be made to effect the dis ensation oi gasoline by inserting a Washer in the coin receiver. Assuming the attempt to have been made. the washer will come to rest. upon the coin stop 43 as does a legitimate coin, but upon pulling forwardly upon the )lunger 4. the look end 48 of the bell-cran( 4G will simply pass through the hole in the washer and thereby avoid displacement of the valve stop 50, which it will be remembered, is a prerequisite to the operation ofthe valve Inasmueh as the hook end 48 as passed through the hole in the washer. the washer will he lullig up or suspended in space. upon the displacement of the coin stop 43.

The forward pull of the plunger 4 rocks a pawl lever 61 upon its pivot 62. The confronting ends of the lug 57 and the pawl (3l arey beveled so that the lug 57 rides past "the pavvl and takes up a position therebehind as in Figure 4 when the plunger 4 is pulled out. The release of the plunger 4 lllll lll.;

llU

l.of the valve plunger 'with an arm 65 extending from the pawl lever 61.' An outward pull of the valveplunger 5, and conse-` quent engagement of the lug 64 with the arm 65, will rock lthe lever 61 upon its pivot and release the lug 57 so that the spring 59 may move the coin stop 43 back toits original position across the coin chute 42 and above the supplemental slug chute 86.

The hook end 48 of the bell-crank 46 opi erates in an aperture in ay fixed plate 66 in front of the cupped end 44. The conjunction of the chutes 42, 86, the cupped end 44, n the plates 66and 43 defines what may aptly be termed a coin chamber 67, because 1t is intothe space thus roughly defined by the parts mentioned that the coin drops for the subsequent action fof the mechanism. The pawl lever 61 is counterweighted at 68, and thetendencyof the counter-weight is to hold the lever against a fixed stop 69.

Variations in the price of gasoline can be compensated. for only by regulating the amount to be dispensed for a gwen sum of moneyglf the price per galloir increases the apparatus must be adjusted to dispense less than four gallons forthe one dollar standard herein adopted. If the price per gallon drops the apparatus must be adjusted to dispense more than four gallons for the one dollar standard. The foregoing price variations are met by adjusting the tube 16, and the adjustments of the tube are made in' reference to the major `four gallon mark 70 on the container 7 (Fig. 1) and in,

reference to the supplemental marks 71 andV 72, respectively above and below the main mark 70.

A pinion 73 (Fig. 5 meshes with a rack 74 on the side of-thetu e 16. The lower encl y of the tube is built with a circular skirt 75 in spaced relationshi with the wall of the tube to 'thereby pro uce an annular recess 76 into which the sleeve 77 upon the upper extremity of the pipe 15 extends. The sleeve is fixed in position by a screw 78. A packing 79 prevents leakage of gasoline at the slidable joint between the skirt and' sleeve 77. Similarly, a gland.v 80 prevents/ or lower the tube 16 in reference to the marks 43 because the coin stop is now held,

-42 and to the coin chamber 67.

on the outside of the container 7 so that more or less gasoline may be dispensed for a given price.

A spring 89 presses between the casingG and an extension 90 on the initiating plunger 1 to push the plunger inwardly when released. The extension carries a roller 91 which is engageable with the lever 92 of the pinion 49 `upon the outward pull of the plunger 1 thereby to insure moving the cup 44 and stop 50 to the proper initial positions.

The extremity of the plunger 1 terminates in a heel l93.

This heel is engageable with a pivoted arm 94 which` upon outward movement ofthe plun er therefore swings to the dotted line position in Fig. 4 thus engaging the arm 65 and swinging the pawl lever 61 downward. This act disengages the coin stop 43 so that the stop may return to proper position in front of the cupped end 44.

A sectional construction of the valve plunger 5 prevents repeating the dispensation of gasoline prior to the insertion of a coin for the lnext purchase. The sections are designated 95 and 96 in order to distinguish them. The first of these has a pin 97 which rides in a slot 98 of the second. The plunger 5 may be pulled out (Fig.n 6) to open the valve 20 (Fig. 7) for dispensation of the gasoline but an inward push of the-plunger with the intention of opening the valve 13 to the tank 7 is defeated by the riding 'of the section 96 relatively to the section 95. The latter re mains fixed in place until the plunger 1 is pulled` out, and with vthat act the parts are so restored that only the insertion of another` aov coin will make possible the further dispen e sation of gasoline.

The operation is readily understood and inasmuch as the parts have been described the cycle of operation can 'be gone through in the order of the various steps.

The spring .89 pushes the initiating plunger 1 inwardly of thecasing 6. It is therefore necessary 4to irst pull upon the exposed part of the initiating plunger prior to the .in sertion of a. coin C into the slot 29. This is necessary in order to move .the section 95 of the valve plunger 5 over to the right of the casing (Fig. 2), thereby opening the inlet valve 13 to theglass container or tank 7 and closing the discharge valve 20-(Fig. 3).

Thisv act of the initiating plunger 1 (Fig. 2) also extends the stop 50 and insures the positioning of the cupped end 44 of the rack 45v in proper relationship to the coin chute 52 assumes a position behind the extended stop 50 and prevents an outward pull of the valve plun er 5. l

Cperation o the pump handle 2 will cause the elevation of gasoline from the under ground tank (not shown) to the container 7 by way of the-pipe 11 and the open inlet p The latch valve 13. The purchaser should Watch the rising level of gasoline in the container (Fig. 1) and stop when such level reaches the upper end of the tube 16. Should he continue operation of the handle 2 the gasoline will simply overflow into the pipe 15 and thus return to the underground tank.

Insert silver dollar C in the slot( 29 (Figs. 1 and 8), and pull the coin plunger 3 out. Upon insertion in the slot 29 the coin is held between the spring 37 and thelever 38 of the coin receiver, and being of the required size will not roll out of the head 30. But a coin or slug of smaller size Will roll out upon pulling the plunger 3, and will fall into the chute 40 whence it passes into the box 41. The pull upon the plunger 3 new transfers the coin receiver from the full line position in Figure 8 to the dotted line position, whereupon the -engagement of the lever 38 with the stop 36 will compress the spring 39 and release the coin which then drops into the coin chute 42 and assumes a position in the coin chamber 67 as indicated by dotted lines in Figure 2. l

The eoin stop 43, being in position, supports the coin C as stated. The coin plunger 3 may now be released. The main plunge: 4 is closed. This act 'rocks the bell-crank 46 so that the hook end 48 presses against the coin C and pushes the rack to the right by virtue of the engagement of the coin with the cupped end 44 of the rack. The motion of the rack 45 turns the pinion 49 in the counter-clockwise direction and displaces or lowers the valve stop 50. The same act of the plunger 4-displaces the coin stop 43 so that passage to the supplemental slu chute 86 is opened. But the coin has alrea y been moved to the full line position in Figure 4 and there is no possibility of the coin drop-r pin in the chute 86. The awl lever 61 ml s the coin stop 43 in the isplaced position by virtue of the engagement of the lug 57 behind the pawl.

A pullon the valve plunger 5 to the left is now in order. The valve stop 5() having been displaced from the path of the latch 52 (Fig. 4) permits such pull so that the valve plunger 5 assumes the position in Figure 6. The action of the plunger 5 will turn the valves 13 and 20 from the positions in Figure 3 to the positions in Figure 7. The previously measured gasoline in the container 7 will run out the now open valve 20. The valve 13 is closed to the upper part of the pipe 11. and should the purchaser continue operation of the pump handle 2 the gasoline passes into the lower part of the pipe 11 and returns to the underground tank by way of the connection 17 (Fig. 7) and the common return pipe 15.

Return of the initiating plunger 1 to the y starting position will be insured by the engagement of the lug 26 with the heel 27 4by the initiating plunger 1, which, upon' being pulled out will cause rocking of the arm 94 by engagement of the heel 93 thercby to 'rock the pawl 61 (sce dotted lines, Fig. 4) and release the stop 43.

Release of the main plunger 4 will result in a relaxation ofthe pressure of the hook end 48 against the coin (see Fig. 4). The

coin is therefore free to drop into the coin chute 87 and into the coin box 88 beneath it. The release of the lug 57 from the paw] 61 ermits thecoinstop 43 to move back in rea iness for the next coin and gasoline dispensing operation as already stated.

Should the purchaser insert a washer of the exact size of a silver dollar the action will be this: The washer will assume a position in the coin chamber 67 as in the case of the coin C (Fig. 2). The subsequent pull upon the main plunger 4 will cause rocking of the bell crank 46, but" the hook ends 48 will pass throu h the hole in the washer and thereby avoi movement of the latch 45 and consequent displacement of the valve stop ao.

An attempt to obtain gasoline by pulling upon the plunger 5 will be frustrated by the engagement o? the latch 52 .with the valve stop (Fig. 2). The pull upon the plunger 4 will also displace the coin stop 43 as before, and the subsequent release Vof the plunger 4 and return of the bell-crank 46 will release the Washer which then drops into the supplemental slug chute 86.

The purpose and mode of adjustment of the tube 16 are readily understood from Figures 1 and 5. The price per gallon of gasoline often luctuates so that the dollar standard herein adopted will not agree if the price varies either above or below the 25 per gallon. The tube is therefore ad justed one Way or the other in reference to the major four-gallon mark 70 (Fig. 1) so that more than four gallons are dispensed if the price drops or less than four gallons if the price increases.
